Transmission of HIV by kissing just doesn't occur--at least it is so rare that nobody has ever documented it, with or without herpes. And your negative test 40 days later is virtually 100% assurance you aren't infected. Official recommendations indeed are to wait until 3 months, but almost nobody who is negative at 4-6 weeks goes on to become positive at 3 months.
Think through the odds (I have done this exercise before, but maybe helpful for people to see it again): Assume there is a 20% chance the guy you kissed is HIV positive. Assume there is one chance in 100,000 you could have got infected. (The actual chance probably is closer to 1 in a million.) Now add that 95% of infected people will have positive tests at 40 days. (It's probably more like 98-99%.) The math works out like this: 0.2 x 0.00001 x 0.05 = 0.0000001, i.e. one in 10 million. That is the

So if you'll feel better having yet another negative test at 3 months, feel free. It will be negative.
